lowercase In Unix like computer operating system s, the code at code command is used to schedule command computing command s to be executed once, at a particular system time time in the future. More precisely, it reads a series of commands from standard input and collects them into one at job which is carried out at a later date. The at job inherits the current environment, so that it is executed in the same working directory and with the same environment variable s set as when it was scheduled. It differs from code cron code which is used for recurring executions e.g. once an hour, every Tuesday, January 1 every year . As with code cron code , many Unix systems allow the administrator to restrict access to the code at code command. code at code can be made to mail a user when done carrying out a scheduled job of theirs, can use more than one job queue, and can read a list of jobs to carry out from a file instead of standard input.

Bell Unix The Programmer s Workbench PWB UNIX was an early version of the Unix operating system created in the Bell Labs Computer Science Research Group of AT&T . Prior to 1976 Unix development at AT&T was a project of a small group of researchers in Department 1127 of Bell Labs . As the usefulness of Unix grew, the company decided to develop a version of Unix tailored to support programmer s in production work, not just research. The Programmer s Workbench was started in 1973, ref name Mashey John R. Mashey 2004 . http queue.acm.org detail.cfm?id 1039532 Languages, Levels, Libraries, and Longevity . ACM Queue 2 9 . ref by Evan Ivie and Rudd Canaday to support a computer center for a 1000 employee Bell Labs division, which would be the largest Unix site for several years. PWB UNIX was to provide tools for teams of programmers to manage their source code and collaborate on projects with other team members. While the PWB group managed their source code on Unix systems, programs were often written to run on other legacy operating systems. For this reason, PWB included software for Batch processing submitting jobs to IBM System 370 , UNIVAC 1100 series, and Scientific Data Systems XDS SDS Sigma 5 Sigma 5 computers. In 1978 PWB supported a user community of about 1100 users in the Business Information Systems Programs BISP group of Bell Labs. Two major releases of Programmer s Workbench were produced. PWB UNIX 1.0, released July 1, 1977 was based on Version 6 Unix PWB 2.0 was based on Version 7 Unix .

A port of Version 6 Unix to the Interdata 7 32 was completed by Richard Miller and Ross Nealon at Wollongong University , Australia , during 1976 1977. This project was supervised by professor Juris Reinfelds . The resulting system was called Wollongong Interdata UNIX, Level 6 . This distribution also included utilities developed at Wollongong, and later releases had features of V7, notably its C programming language C compiler . Wollongong Unix was the first ever port to a platform other than the PDP series of computers, proving that portable operating systems were indeed feasible, and that C was the language in which to write them. In 1980, this version was licensed to The Wollongong Group in Palo Alto that published it as Edition 7.
